Abstract

Abstract: The extraction of alkaloids from the stem of Solanum melongena Linn. with Soxhlet method was investigated. Content of alkaloids was determined by acid-base titration. The factors of organic solvent,solid-liquid ratio,the time of extraction and the pH value of solvent were studied. The optimal extraction conditions are: 60% ethanol as solvent, the solid-liquid ratio is 1:5.5, pH value is 3, and the time of extraction is 3 h. The average content of alkaloids was 1.96%. The extaction result was stable and repetitive.

Key words: Solanum melongena Linn., alkaloids, extraction, titrimetric method
